First, identify the type of door knob you have (there are three common types), and then take a look at its locking mechanism. Typically, the knobs on your door have exposed set screws to secure them to the spindle, but there are also some models that use screws inside the rose to secure the handle. 

Those screws might need to be tightened or loosened to ensure that your doorknob is working correctly. This can be done easily with a screwdriver. 

Next, check the latch and door striker plate for signs of rust or damage that could be causing the lock to malfunction. Rust can be removed with a wire brush and then lubricated with WD-40 or a similar dry lubricant to help the lock function properly again. 

Another option is to disassemble the lock entirely and examine it for any damaged components or faulty wiring that might be causing the problem. If you’re not confident about working on such an intricate mechanism, or if it requires an experienced professional, don’t hesitate to contact a local locksmith. 

The most likely reason why a door knob is stuck is because of a worn spring or another component within the lock. You might be able to fix this with a new spring, but there’s a chance that it’s just time for a replacement knob. 

If the doorknob is still sticking, lubricate it with a small amount of graphite. This will make it easier for the key to insert and the handle to turn smoothly. If this doesn’t work, try squirting some lubricant into the seam around the handle where the lock toggle or thumb button connects with the doorknob mechanism. 

Finally, if you’re having trouble unlocking the door, test it by pressing the button on the knob with a finger to see if you can get it to release quickly and easily. Do this like you would an arcade video game button, and jiggle it vigorously if it is still not responding to your efforts. 

This should be enough to solve the problem for most people, but if you’re not comfortable working on a knob that’s a bit old or difficult to locate, consider hiring a professional locksmith to take care of it. 

If you’re a do-it-yourselfer, you may be able to repair your doorknob lock for much less than the cost of replacing it. This is especially true for older knobs and handles, which are often cheaper to replace than newer ones. 

If you’re dealing with a vintage doorknob that’s stuck, it might be a simple case of a loose set screw. Locate the screw and apply a little lubrication to it with an application straw. If that doesn’t help, replace the spindle or tighten the set screw until it’s securely in place.
